Mum lived in Ireland for over 30 years but held onto her Scottish accent. I would always forget she had a different accent until she met people for the first time and they would always comment on it. Mum never really lost her blás, but whenever she went to Scotland for the weekend to see her family she would come back with a markedly stronger accent than before, a kind of tonality top-up.
After having all of us and living in Ireland for more time than she had lived in Scotland Mum began to identify herself as Irish. She still retained strong links with Scotland, as the majority of her family were still there but she saw Ireland as home. Mum was an Irish woman with a Scottish accent in Ireland, and a Scottish woman with an Irish accent in Glasgow. You cannae win!
Mum was born and bred in bonnie Scotland and like many of her countrymen & women who left Scotland, she never really lost her accent. Mum had by the end of her life lived more time out of Scotland than she had in it, and had lived in Ireland for over 25 years. Despite this we’ve all inherited some Scottish-isms, such as saying ‘wee’ when we mean little, and for saying ‘booook’ and ‘cooook’ instead of the local Dublin vernacular of ‘buk’ and ‘cuk’ which we were surrounded with growing up.
